Correct Answer
D. Protein
Explanation
A carnivore's diet is mostly made up of protein because carnivores primarily eat meat, which is a rich source of protein. Protein is essential for carnivores as it provides the necessary amino acids for growth, repair, and maintenance of their bodies. It also helps in the development of muscles, bones, and other tissues. Carnivores have specialized digestive systems that are adapted to efficiently process and absorb protein from their prey. Therefore, protein is the main component of a carnivore's diet to meet their nutritional needs and support their carnivorous lifestyle.

What is the name given to a baby insect?
Correct Answer
C. Larva

What do we call a series of changes an animal experiences during its life?
Correct Answer
B. MetamorpHosis
Explanation
Metamorphosis refers to a series of changes that an animal undergoes during its life, typically involving a transformation from one form to another. This process is commonly observed in insects, such as butterflies and beetles, where they go through distinct stages of development, including egg, larva, pupa, and adult. The term "metamorphosis" accurately describes the phenomenon of a complete transformation in an animal's physical appearance and behavior as it progresses through different life stages.
8.
A cocoon is …
Correct Answer
B. Tough and silky
Explanation
A cocoon is tough and silky because it is made up of a strong and durable material called silk. Silk is produced by certain insects, such as silkworms, to create a protective covering for themselves during their pupal stage. This silk is strong enough to provide protection from predators and environmental factors, while also being smooth and silky in texture.

What is a producer in a food chain?
Correct Answer
A. An organism that makes their own food
Explanation
A producer in a food chain is an organism that is capable of producing its own food through photosynthesis or chemosynthesis. These organisms, such as plants or algae, convert sunlight or inorganic compounds into energy-rich organic molecules. They are the primary source of energy in the food chain and provide food for other organisms, such as herbivores. Therefore, the correct answer is "An organism that makes their own food."
10.
What does a food web show?
Correct Answer
B. Several food chains joined together to make one
Explanation
A food web shows several food chains joined together to make one interconnected system. It illustrates the flow of energy and nutrients through different organisms in an ecosystem. It demonstrates how each organism is connected to multiple others through their feeding relationships, highlighting the complexity and interdependence of the ecosystem.
